What is ThermoPhos?

ThermoPhos is a Fused Calcium Magnesium Phosphate, it's made by melting phosphate rock and serpentine rock together and then cooling it rapidly with water. ThermoPhos is New Zealand's only glass phosphate fertiliser. Glass fertilisers are controlled release fertilisers, supplying nutrients on a year round basis instead of all and then nothing. Glass fertilisers are the way of the future.
NelisFert is the exclusive importer of ThermoPhos into New Zealand.

Why is our ThermoPhos so great?

At over 90% citric soluble, it's more reactive than Dicalcic, RPR or Guano.
It's free-flowing, stores very well and is non-corrosive.
It has a pH of 10 and with a liming equivalent of more than 80%, it limes your soil.
ThermoPhos is an excellent source of Phosphorus, Magnesium and Calcium. These nutrients get released throughout the year providing a steady source of nutrients for plant uptake. This incudes year round Magnesium for animal health.
Low in Cadmium - At 14mgCd/kgP it contains 20 times less cadmium than superphosphate and 19 times less than Sechura RPR.
It's a great source of soil/plant available silicon.
The particle sizes of ThermoPhos are less than 2mm in size, like coarse black sand. Because of this, the fertiliser particles are able to wash into the soil. This reduces phosphate runoff at times of soil erosion.

ThermoPhos has been independently tested

ThermoPhos has been independently tested by Eurofins in Auckland, by SpectraChem Analytical in Wellington and by Thornton Laboratories in America.
Thornton Laboratories use the 5 day Sodium Carbonate - Ammonium Nitrate extraction method to test for soluble silicon content in solid fertiliser. This extraction method is the only legal soluble silicon test in the US and is an internationally recognized test method.
